Answer:
Step-by-step explanation:
a) r = 10/2 = 5 feet
Area of floor =πr² =3.14*5*5 = 78.5 feet²
B) h = 3 foot
Volume of cylinder = πr²h = 3.14*5*5*3 = 235.5 cubic feet
Volume of hemisphere =2/3πr³= 2*3.14*5*5*5/3=261.67 cubic feet
Volume of space inside the observatory = 497.17 cubic feet
 
        
             
        
        
        
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X 
X = 32.
check 
10(32)+180 = 500
320+180 =500
500 =500...confirmed

A producer is said to have an absolute advantage over another producer when he required less amount of input to produce the same good compared to the other producer.
While a producer is said to have a comparative advantage over another producer when he produces his goods at a lesser opportunity cost compared to the other produer.
Here, time is one of the inputs used in production and Maria produces a scarf at a lesser time compared to Sofia. Thus, Maria has an absolute advantage over Maria in the production of scarves.
Therefore, the true statement is "<span>Maria has an absolute advantage over Sofia".</span>
